Mr.Longarm is a bouldering area in Los Penasquitos Canyon Preserve, a city-managed preserve in California. It sits among a cluster of climbing areas, with Face Climb, Del Poconitos and Still Waters Run Deep all about 0.1 mile away, and the North Side Trail also within a tenth of a mile. The preserve's bouldering is all on the same scale, with eight routes ranging from V0 to V9. The easiest is Poison Oak Vigilante at V0, and the hardest is Tax Evasion at V9. The median grade is V4, so climbers can find problems at every level of the V scale. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station show May highs around 72°F and October highs around 78°F, with only a few wet days in each. Summer runs warmer, with August highs near 82°F. The San Diego Sea to Sea Trail passes within a mile, and the San Dieguito River, about 7.5 miles away, offers paddling.
